I have had the none issuance of a BP numerous times, from outstations, and it is usually down to system limitations, or issues generating the BP..
However I would never tell someone how to do there job, or say it worked before, this only gets staffs backs up... and hence why they felt threatened by someone being very argumentative.
In the end it takes 2minutes to get a connecting BP, so not sure why people get so het up about it...
I dont see why this is newsworthy, man argues with Staff and gets a letter to calm dowm, maybe one for the daily fail or the scum,the scam, the sun.
